Thinking my way toward the ideal sheet metal brake.

a generic pan.

There is a term called “paralysis by analysis”. It is the trap a person can fall into trying to create perfect and never getting anything done. However, there is also a term for going out and purchasing something that sounds great, and then finding it will not do the job. It

Using Manufacturers drawings in LibreCAD

A manufactures drawing being used in LibreCAD

Many manufacture’s have dxf files of their products available for download. These can be used in LibreCAD as well as the high-priced proprietary CAD programs. In the embedded video I show how you can download and use these files for components in your projects.

The example I

Creating Scaled Borders for LibreCAD

The Base drawing – scaled to create the others.

I have created scaled borders for North American letter size paper and am making them available for download. The problem with scaling drawings is it is relatively easy to scale the borders, but the hassle comes with scaling the dimension text and arrows. By creating

Brains not tools… Making an Enclosure for Electronics.

Step 1 Create the Plans.

Sometimes you just gotta do it yourself. Even if it probably makes no sense to do it. I spent a big part of the weekend building an enclosure box for the power-supply I have been using with the thermistor board. However,I consider it a success and I learned a

Printed Circuit Boards – Part II of Creating our Masterpiece.

A Recent Built Electronic Kit.

Last night I discussed the basics of laying out a circuit board. Tonight I will discuss some about how boards are constructed. The picture to the right is a fairly simple printed circuit board, PCB, that came as part of an electronic kit I recently bought. It will be

Making our Electronic Masterpiece

The Final Thermistor Circuit.

The hard part of our electronic design is over… Well sort of. We are just moving into a new phase of it, but at least we will not be talking theory. Finally we are actually going to mount parts to something and start thinking about how we will get it

Where is the biggest bang for the buck in solar energy?

Solar Energy Concepts

Tonight I thought I would start pointing the direction we will be going toward solar energy. Like in all projects the first thing to determine is where do we want to go. I am going to make the first assumption. We want to use our money in the most effective way

Efficiency and Effectiveness and Solar Energy.

Tonight’s post was intended to kick-off a discussion about solar energy, but as I was formulating how I was going to present it I kept running into a word … efficiency. I know the thermodynamic use of the term very well, but we often throw the word around to mean lots of other things. That

A problem with scaling, and the popsicle stick project

Picture 1: Getting a feel for the strength of glued popsicle sticks

The whole idea of working with popsicle sticks was that they are relatively inexpensive and require little work space. I thought that it may be helpful to people little money and space to work with something to get some experience designing and

Episode 55 – Assumptions

$100 invested over time at various interest rates

In this podcast I discuss assumptions and how they are often hidden and can often mess up your day and your design. Assumptions are everywhere and usually they are not mentioned. The worse case of the problem is if these are hidden in a software algorithm
